If your guilt over driving an SUV or some other big clunker is too much to bear, you can do what I just did: Buy a carbon offset.
To make amends for wasting fuel, donate to an environmental project that helps society conserve energy or reduce emissions.
For instance, if you purchase an SUV offset at envirocitizen.org, your donation funds the Greater New Bedford Landfill Gas Utilization Project, which uses greenhouses gases seeping from the landfill to fuel generators that produce electricity.
You can find several offset programs online some reward you with bumper stickers but I picked EnviroCitizen because it supports a local cause.
Maybe now the carbon-footprint police will leave me alone.
